To allwiioinii may concern:

Be it known that I, ANGELO JosLER, a citizen of the United States,and aresident of Chicago, county of Cook, and State of-Illinois',- haveinvented certain new and useful Improvements in WVindow-Guards, of whichand exact description. I

-Th1s invention relates to window guards, and its princip'alob]ects areto provide a 1 guard 'which may be easily and quickly 2 sash.

usual and well known manner. I

The window. guard comprises an Open ably mamaa in the; window frame inthe work removable. guard 'prO'per I6; and its supports 17 which arefastened to the side 1nembersl2,'of the window frame by screws orotherwise. Said supports are shown as comprising upright hannel ironbars 18,;

ing lock memberQO, which is pivotally secured to the bar by a rivet orother pivotal connection 21. A short bar 22, spaced from the bar 18, bytwo blocks 23, 24, stands at the side of each lock member 20, and pievents side play of the latter; The bar 22,

otherwise rigidly secured together. u Each lock member 20, comprises anupstanding stem portion 25, through which the pivot pinextends,zano'tched hook like front portion 26, the forward edge of whichis curved and inclined (see Figs. 5am? and] a tail piece 27, which; isCapable of'extend in g'over the top of the lower sash when in] itsunlocked position, and also is capable ofstanding'in front of anuprightmember of the lower sash when the latter is partly raised; theblock 23, serves as a stop against which the tail piecestrikes' when thelock member is rocked forward See Fig. 5.)

The: window guard proper 16, may Ooin prise-any suitable grille or openwork construction', and in its simplest form have and 'hori'zoiital'nenibers 29, whi ch'may be united at their lntersect'ions. by rivets orby welding theinieinbers together as mayj be found desirable. "uprightand hori zontal-ineinbers may'cfojnsifst of flatbars' or otherwise an d'theframe thus formed of occupiedby thelowersash? M J The upright endm'ember30, -of the guard a sine to coverthe'.majorlportion ofjthe spaceblocks-2 3, 24,.and bar 18, are'riveted or shown, it. as nipr i i pr ehe'int lr ev d iat-e members 28, upright end. members 8O,

proper, engage with the lock members 20, and the hooks 19, and arethereby secured to the window frame as-will be hereafter set forth. Saidend members are preferably secured to the main body of the guard properin an adjustable manner, whereby the same guard may be adjusted toaccommodate windows of various widths. This adjustable connection maycomprise yoke shaped members 31, one secured to each upright end bar 30,as by rivets or by being welded thereto, and the horizontal arms 32, ofsaid members 31, slide in brackets 33, that are riveted or otherwisesecured to the upright end bars 28. I The vertical bars of themembers31, have clips 33*, secured thereto as by screws, 34, the end portionsof which clips lie on the side of the horizontal bars 29, opposite tothe upright bars of the members 31, so as to slidably connect themtherewith. By tightening the screws 34, the main grille or guard 16, andextension are rigidly secured together.

For the purposes of vertical adjustment, the bars 30, may be providedwith notches or slots 35, 36, for the reception of the hooks 19, andlock members 20. There may be one slot 35, at the top of each bar 30,and one at the bottom thereof, but I have shown the several slots atboth ends arranged one above the other for the purpose of verticaladjustment of the guard to accommodate win dow openings of variousheights. In use the upper edge of a slot 36 in each bar 30, rests on ahook 19, directly behind the bill thereof, whereby the guard issupported,

and each lock member 20, overhangs the lower edge ofa slot 35, in eachbar 30, with its bill in front of the bar. WVhen the lower sash ispartly raised, it stands innnediately behind the tail piece 27 of eachlock member (see Figs. 4, 5 and 7), thereby preventing movement of thelock members toward the lower sash. Consequently since the bills of thelock members lie in front of the barsv 30, the latter cannot be movedforward to disengage them from the lock members, said bars cannot beraised because the lower edges of the slots 35 will strike against theundersides of the portions 26, of the hook members and asthe lattercannot move upward or toward the sash,the bars cannot be. raised todisengage them from the hooks 19,

or look members 20.

To detach the guard from its support and lock'members, the lower sash isfirst closed; the guardis then raised, thereby swinging the. lockmembers toward the sash, after which those parts of the bars. 30,immediately vbelow the slots 35,- in which the lock members 20, arelocated, enter the notches in the portions 26, of thelock members andthis movement of. the bars 30, into thenotches in the lock memberspermits of their disengagement, at their lower ends,

with the hooks 19, whereupon the lower end of the guard may be movedbackward toward the person, to free the guard from the hooks 19, afterwhich .it may be lowered and disengaged from the lock members.

To replace the guard, the lower ends of the bars 30, are placed upon thehooks19, I

In the modified form illustrated in Figs.

8 to 11 inclusive, the horizontal arms 32*, of the extension members,31%, are bent back at their ends as shown. in Fig. 11, and riveted toupright flat bars 32", in place of be ing secured directly to the endbars 30. The fiat bars 32", are adjust-ably secured. to the end bars30*, by screws 32, whereby the body portion of the guard may be raisedor lowered with respect to the end bars 30*. A plurality of screw holes32 are provided in the bar 32 to afford the vertical adjustment of thebody portion of the guard. In place of the slots 35, 36, shown in Fig.1, notches 35 36 are provided at the 11pper and lower ends of said barswhich notches are arranged for they reception of the lock members 19,andv hook members 20 respectively. In other respects, the constructionis substantially the same as that shown in the other form of theinvention.

To provide for an extra wide range of adjustment, withoutleaving toolarge gaps between the end upright members, 28, and the bars 30,additional filling in bars 28?,

' may be employed which may be attached to the member 31, of the guardproper if sov desired. As here-shown, the bar 29 is attached to theupright bar 32", by a screw 32", the head. of which is covered by thebar 30 to preventunauthorized removal and the;

the upper meetingrail as shown in Fig. 12,. k

and in such cases anopening orv hole 15 may be formed in each of saidprojecting end portlons for the reception of the tail pieces of thelock'member, or as an alternative, a block may be secured totheextension to provide a flat end on the sash.

I am aware that there are other alterations and modifications of theinvention later displayed without departing from the spirit ofthisinvention. I desire, therefore, not to limit'myself to'the eXact formsofConstruction shown and described, but intend in the following claims topoint out all of the invention disclosed herein. 1 -I' claimas new anddesire to secure by Let ters Patent: I I
